Getting Started

Criteria for Testing

Whenever there is a decision to be made about chemotherapy or treatment options, the EVA-PCD assay can help identify, from many comparable choices, the most effective and least toxic treatment for you. Whether you are newly diagnosed, experiencing a recurrence or your current chemotherapy is no longer effective, we can help.

Specimen Criteria

To ensure the accuracy of our results, the patient should be 2 - 4 weeks outside of any recent chemotherapy at the time of specimen collection. Recent treatment exposure may interfere with the EVA-PCD results.

Solid tumor: A minimum of 1 gm/1 cm of viable malignant tumor tissue is needed

NOTE: Needle biopsies DO NOT provide the quantity/quality of tumor required for an accurate EVA-PCD analysis.

Malignant Effusions: 500-1000 ml of heparinized, cytologically positive pleural or ascites fluid.

Blood (Leukemia) Specimen: 7 – 10 ml of peripheral blood in EDTA tube

Bone Marrow Aspirate (Leukemias and myelomas): 1 – 3 ml of heparinized bone marrow aspirate

The specimen must be received at Rational Therapeutics’ laboratory within 24 – 36 hours of collection. Contact the laboratory to order a specimen transportation kit.

If shipping on Friday, please contact the laboratory for specific instructions.
